UNITED STATES DAVID C. BAUGHMAN,

PATENT OFFICE.

OF ALBION, INDIANA.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 251,509, dated December 27, 1881.

Application filed October 24, 1881. (No model.)

To all whom it may concern:

Be it known that 1, DAVID C. BAUGHMAN, of Albion, in the county of Noble, and in the State of Indiana, have invented certain new and useful Improvementsin Lanterns; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to an improvement on lanterns for street-lamp posts, brackets, and other purposes; and the nature of my invention consists in a swivel-cap provided with openings on one side and a weather cook or vane, in combination with a lantern-top, as will be hereinafter explained.

In the drawing hereto annexed I have represented my improvement applied to the tubular cap of a lantern designed for use .on railroads. I

This invention relates to an improvement on cowls, which are designed for use on railroadlanterns, lanterns for street-lamp posts, bracket-lanterns, and for all lanterns which are exposed to strong currents of air.

The nature of my invention consists in the combination, with a lantern-chimney or out-letpipe, of aswivel-cylinder perforated on one side and provided with a weather-vane, whose feathered portion is on the said perforated side of the cylinder, the said chimney or outlet-pipe being annularly grooved and screw-threaded above the groove, and the said cylinder being provided with screw-threads through the opening in its bottom, as will be hereinafter explained.

The tubular portion A is designed to represent the top of the tubular frame of a railroadlantern, and the tubular portion B designates the chimney or outlet-pipe for the heated products. This outlet-pipe B has an annular groove, it, formed in it near its upper end, and abovethis groove is a short screw-threaded portion, a.

B designates a cylindrical cowl, having a circular opening through the center of its bottom, in the edge of which a female thread, i, is tapped, adapted to screw on the male-threaded portion a of the outlet tube or pipe B. By these means the cylindrical cowl B can be adjusted so that it will swivel freely in the groove it, but will not be liable to detachment from cowl B in the severest gale of wind. By simply lifting the cowl until its threads 1' engage with the threads on the pipe B the cowl can be detached from the latter by unscrewing. When the cow] is free to turn around the pipe B in the groove 70 thereof, it is supported on the center point, J, fixed to said pipe.

E designates a weather-vane, which is rigidly secured on top of the cowl B by means of a male nut, G; and b designates draft-openings made through the wall of the cowl B on the same side thereof as I locate the feather-e of the vane E.

It will be seen that while my cowl is free to turn about the outlet-pipe B by the currents of air acting on the feather of the vane the cowl is positively prevented from casual detachment from the chimney or outlet-pipe of the lantern. I may enlarge the flangeg of the cowl so as to form a water-shed to prevent the rain from entering the lantern through the draft-openings b.

I claim as my invention- The combination, with the annularly grooved and screw-threaded chimneyB of alantern, of the center point, J, the cowl B, screw-threaded at "i, perforated at b, and the weather-vane rigidly secured to the top of the cowl, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 19th day of 0ctober, 1881.

DAVID C. BAUGHMAN.
